Hi friends again, my name is govind and I m going to express my words on parallel space application. This application is best to use multiple social network account in a single device but there are few disadvantages too. First one is that this app occupies the large space in your internal storage even if its apk size is few MB that limits the installation of other apps in the device, this the major drawback of this app. Second thing is that parallel space app sometime does not work in background processes, that means you may not know if you have a new massage on second account or not until you open it, this is opposite to original account in which you dont have to open the concerned app to find out if you have a new massage or not. This app requires lot of RAM which also limits the performance of your device. If you are using high end device having 3 to 4 gb ram and 32 to 64 gb internal space then this is the best app to use multiple accounts.
